<p>PURPOSE:To prevent unnecessary power consumption in case of erroneous turning-on of a power switch during carrying by constituting a device so that information of the power switch is ineffective at the time of closing a cover switch. CONSTITUTION:An engaging part 41 is provided on the inside of a cover stopping button 4 and is engaged with a projecting part 21 attached to t cover 2 to stop the cover. These projecting part 21 and engaging part 41 are made of a conductive member and form a cover switch 5. When the cover switch 5 has the projecting part 21 and the engaging part 41 engaged, a conduction signal indicating this state is transmitted to a data processing part. Consequently, as operation signal for detachment of a cover clip 3 is outputted as the turning-off signal of the cover switch 5 when the projecting part 21 and the engaging part 41 are not brought into contact with each other. Thus, the problem is resolved that a power source is turned on again against user's well at the time of applying a pressure to the vicinity of the power switch by some cause and battery is unnecessarily consumed.</p> |
